Key Features
Hardware Flash Encryption Made Easy
The application leverages the ESP32's built-in hardware encryption engine to protect your intellectual property. No more complex command-line workflows - everything is just a few clicks away.
User-Controlled Keys: You generate and control your own encryption keys (not auto-generated)
One-Click Setup: Flash encryption with a single button click
Visual Status: Real-time display of encryption status
Security Fuse Management
Protect your production devices by permanently disabling debug interfaces:
Disable UART Download Mode (prevents unauthorized flashing)
Disable JTAG Debugging
Disable UART Flash Encryption/Decryption
All fuses are one-time programmable (OTP)
Universal Flashing
Flash all ESP32 firmware components in one operation:
Bootloader
Partition Table
Application Firmware
Smart Workflow
The application automatically detects your ESP32's encryption state:
Fresh Chip: Guides you through complete encryption setup
Encrypted Chip: Uses hardware encryption for fast, secure updates
Status Display: Real-time chip information and encryption status
Screenshots
Main Interface
Clean, organized interface with clear sections for flashing, encryption, and status monitoring.
